I'm so sorry to hear that, Larissa. I've had to rewrite lost words in the past, and at first the task is daunting. But I found that instead of trying to write the exact same words, if I instead focused on recapturing the scene and how I wanted it to feel, it often came out better.
It's actually what inspired me later to rewrite a novel from scratch, which was a huge learning experience for me.
I wish you all the best in the rewrite.
